An improved structure for providing flexibility for holding and mounting components, such as microscopes and cameras, in order to eliminate disruptions from undesirable vibrations and tilting of the mounted component. In the transparentscattering state switching element, two transparent substrates are provided parallel to and separated from each other, and an electrode is provided to the surface of each transparent substrate. The tactical module divides the air space around the aircraft into advisory, caution, and warning zones and for each provides display, tone and voice alerts to facilitate pop-up avoidance guidance commands.
